Aim7 SARH 2 Port ASR Muzzle Brake — 1/2×28 Thread The Aim7 SARH 2 Port Muzzle Brake is a precision-engineered muzzle device designed for recoil reduction and improved muzzle control on small-bore rifles. With its 1/2×28 thread pitch and dual-port design, it is ideal for platforms chambered in .223 Rem, 5.56 NATO, and similar calibers. Constructed from SUS303 stainless steel, it delivers excellent durability, machinability, and corrosion resistance. Compact yet effective at 1.650″ overall length, the SARH brake provides shooters with a balance of performance and reliability. Key Features Thread Pitch: 1/2×28 — standard threading for .223 / 5.56 platforms. 2-Port Design: Dual side ports reduce recoil and muzzle rise for faster follow-up shots. Material: SUS303 stainless steel — excellent machinability and good corrosion resistance. Dimensions: Overall Length: ~1.650″ Bore Size: 0.368″ — confirm compatibility with your caliber. Finish: Stainless steel, resistant to carbon buildup and environmental wear. Compatibility Firearms: Barrels with 1/2×28 threaded muzzle Calibers: Up to .223 Rem / 5.56 NATO (.368″ bore) Not Recommended: Use with calibers larger than bore size (e.g., .30 cal, 9mm) without professional assessment Suppressor Compatibility The SARH 2 Port Muzzle Brake is designed to work seamlessly with the 13/16×16 ASR Adapter, enabling compatibility with SilencerCo’s ASR (Active Spring Retention) mounting system.
